The Glock company's newest generation of pistols (G42/43, Gen5) is equipped with so-called "Glock Marksman Barrels" (GMB). These barrels feature an enhanced polygonal profile with right-hand twist and a small rifled profile on either side of the main polygonal field impression (Hernandez et al., 2016). Up until now, using the usual methods of comparison (automatic ballistic identification systems, ABIS and comparison microscope) it was difficult to assign bullets fired from a polygonal barrel…

TLDR
Although there are differences in the stresses and strains obtained, similar velocity and pressure parameters are achieved in the two types of barrels, which has application in the development and standardization of new kinds of barrels and weapons.
Manufacturing of firearms parts: Relevant sources of information and contribution in a forensic context
TLDR
The manufacturing processes used to produce the main parts of firearms in contact with the elements of ammunition are presented and an updated list of processes used by specific manufacturers is included, relying not only on the literature but also on the manufacturers themselves.

Glock Marking Barrels – An Evaluation of Individual and Subclass Characteristics
Glock Inc. recently replaced the Enhanced Bullet Identification System (EBIS) with what Glock refers to as the Glock Marking Barrel. Casts and test fired bullets from thirty-five Glock Marking Barrels
Slight variations of breech face marks and firing pin impressions over 3070 consecutive firings evaluated by Evofinder®.
TLDR
Analysis of cartridge cases fired from five Chinese Norinco QSZ-92 9×19mm pistols found variations of marks from the same firearm have not exceeded the differences between marks of different firearms and have not hindered the Evofinder® to make nearly 100% correct correlations.
